CONCRETE RAILWAY-TIE.

Specification of Letters Patent.

Application filed May 13, 1910.

Patented July 18, 1911.

Sera] No. 561,031.

To all whom Li 'may concern:

Be it known that I, WILLIAM I-I. FRUYN, Jr., a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented a certain new and useful Improvement in ConcreteRailway- Ties, of which the following is a specification.

My invention relates to improvements in concrete railway ties and hasfor its object to provide ties independent of the required distancebetween adjacent means for connecting the rail and tie.

It is illustrated in the accompanying drawings, wherein- Figure 1 showsa plan view of a rail in connection with a concrete tie; Fig. 2, asection on an enlarged scale on line 2-2 of Fig. 1; Fig. 3, a sectionalong line 3-3 of Fig. 2; Fig. 4, a plan view of the tie with the railremoved; Fig. 5, a plan view of a double rail showing the ties; Fig. 6,a plan view of a modification; Fig. 7, a side elevation of Fig. 6,

Like parts are indicated by like letters throughout the several figures.

A is the rail, B, the body of the tie, preferably having the reinforcingrods B1, B1, embedded therein,

C is a plate preferably of wood and of any desired thickness, resting ontop of the tie and furnishing a bearing place for the rail.

l), D are securing plates adapted to over hang t-he fiange of the rail.

E, E are bolts having nuts E1, El, and heads E2.

The apertures or slots F are located in the tie parallel with its axisat a point intermediate the center of the tie and the outer edge, andterminate at the bottom in the longitudinally disposed pocket F1, whichis about the size of and engages the bolt head E2, and terminate atopposite ends in the vertical pocket F2 at right angles with the pocketF1. The angle bar G completes the joint in the rail A and rests upon theties. The skirt of the bar comes down and incloses the rail flange andit is necessary that the bolts be spaced farther apart than when theyengage the rail alone. This is provided for by the aperture or slot F.

Fig. 5 shows the rail I-I having the base of its flange in immediatecontact with the flange of the rail A, the two rails being separated bythe spacers H1 and connected by the bolt H2. The rails are held down bymeans of the bolt E and plates D in the usual manner, the pocket or slotF permitting the displacement of the bolts to compensate for theincreased width of the flange.

Figs, 6 and 7 show a tie wherein, instead of the vertical pocket F2, isfound the horizontal pocket J in the side wall of the tie at rightangles to the pocket F1.

It will be evident that while I have shown in my drawings an operativedevice, still many changes might be made both in size, shape andarrangement of parts without departing materially from the spirit of myinvention.

The use and operation of my device are as follows In the use of concreteties, it has been customary to provide them with holes for therail-holding bolt. The location of these holes was fixed at the time thetie was made, and no flexibility or adjust ability allowed. In order,however, to use ,these ties beneath the angle bar or beneath a doublerail of increased width or in connection with a switch or frog, it isnecessary that provision be made for changing t-he position of the bolt.This I do by substituting for the usual circular bolt hole an elongatedbolt slot, this slot being parallel with the axis of the tie. The boltmay be moved back and forth in such slot to compensate for the width ofthe rail base. I provide a pocket at the base of this slot and parallelwith it to hold the bolt head and provide at one end a pocket connectingthe inner pocketwith the outside of the tie, thus permitting theintroduction of the bolt head in such bolt-holding pocket.

I claim:

1. A concrete tie bolt engaging portions and means for adjustablysupporting the bolt within such portions, said means comprising a boltengaging slot and a pocket in connection with said slot and both withinthe body of the tie.

2. A concrete tie bolt engaging portions and means for adjustablysupporting the bolt within such portions, said means comprising a boltengaging slot and a pocket parallel with and in connection with saidslot and both within the body of the tie.

3. A concrete tie having a vertical bolt engaging slot parallel with thea-Xis of the tie and a thin lateral nut pocket beneath and parallel withsaid slot, a connection between said pocket and the exterior of the tielarger in cross section than and connected With the bolt engaging slot.

L1. A concrete tie having a vertical bolt engaging slot parallel withthe axis of the tie, a thin lateral nut pocket beneath and parallel Withsaid slot, and a vertically disposed pocket at right angles to saidlateral pocket.

5. A concrete tie having a vertical bolt engaging slot parallel with theaxis of the tie, a thin lateral nut 'pocket beneath and parallel withsaid slot, and a vertically disposed pocket at right angles With saidlateral pocket, said pocket in connection With said bolt engaging slot.

6. A concrete tie having a vertical bolt en gaging longitudinallydisposed slot and a thin lateral nut pocket beneath and parallel Withsaid slot, both of thein Within and integral With the body of the tie.

7. A concrete tie having a vertical bolt en* gaging longitudinallydisposed slot, a thin lateral nut pocket beneath and parallel with saidslot and a vertically disposed pocket at right angles to said lateralpocket, all of thein embedded Within the concrete body of the tie.

8. A concrete tie having a plurality of vertical bolt engaginglongitudinally disposed slots, nut pockets beneath and in line With saidbolt engaging slots, said slots terminating in pockets of relativelyincreased cross section, said slots and said pockets completely embeddedWithin the body of the tie.
